9b0687e6df add buffer allocation and deallocation calls to the allreduce routine, so 
I can start debugging the memory management code.  The allreduce fucntion
 does nothing at this stage.

906e8bf1d1 Replace the ompi_pointer_array with opal_pointer_array. The next step 
(sometimes after the merge with the ORTE branch), the opal_pointer_array
will became the only pointer_array implementation (the orte_pointer_array
will be removed).

213b5d5c6e Per long threads on the mailing list and much confusion discussion 
about linkers, have all OPAL, ORTE, and OMPI components '''not'' link
against the OPAL, ORTE, or OMPI libraries.

See ttp://www.open-mpi.org/community/lists/users/2007/10/4220.php for
details (or https://svn.open-mpi.org/trac/ompi/wiki/Linkers for a
better-formatted version of the same info).

fd51d9cf28 The call to opal_list_insert() had an off by one error (I think), causing selected components to get lost with certain load orderings. 
I went ahead and rewrote the code to use opal_list_insert_pos() instead, which gives a cleaner flow and more speed.

f92d9097d8 Some more changes to update to coll v1.1.0 that were missed 
yesterday.  This actually exposed a very, very long-standing bug where
part of the coll base was incorrectly checking the coll API version
against the MCA API version.  When coll went to v1.1 (yesterday) and
was no longer the same as the MCA v1.0, the test started failing.

This commit fixes to check for v1.1 everywhere in the coll base, and
to ensure to check coll framework/API version numbers against coll
framework/API version numbers (vs. against the MCA API version
number).

1b66a52c50 Modifying type of binomial tree used for binomial reduce: 
switching:
       0                         0
     / \ \                     / \ \
	1    \ \         -->       4   \ \
  /      \ \                 /     \ \
 3       2  \               3       2 \
             4                         1
(duh).  The first form is the bmtree suitable for bcast, but the latter is better for reduce.

3740640711 Modifying MPI_Gather in tuned module: 
- adding linear algorithm with synchronization for gather.
  This algorithm prevents congestion at root process, but introduces 
  synchronization (serializes non-root processes, but allows messages 
  to arrive from two processes at the same time).  
  It performed better than binomial and linear algorithms for large message, 
  and intermediate and large communicator sizes.
- Updating MPI_Gather decision function to reflect performance results
  from MX.  I will perform more measurements though - so this one can 
  change.
